对于每个整数n,设Sn是所有类数项h(K)/h(K?)对于数域K和K?本文将给出有限集Sn,对小的n给出一些明确的结果。例如,对于每个x?与n?15,x或x-1是一个整数,是一个素数幂除214?三十六个?53.
For each integer n, let Sn be the set of all class number quotients h(K)/h(K?) for number fields K and K? of degree n with the same zeta-function.In this note we will give some explicit results on the finite sets Sn, for small n. For example, for every x ? Sn with n ? 15, x or x-1 is an integer that is a prime power dividing 214 ? 36 ? 53.
